i ran a 12.89 at 108.574 with a 2.09 sixty on my sumitomos with a m6 car stock suspension mods are lts,solid motor mounts and prothane t mount,spec stage 3,and billet flywheel with ram adjustable master,and lid all egr and air is removed and the cats removed also.just wondering with a good set of tires and a tune what my car is capable of. thanks for any input

 

Hard to get a good ET on street tires with an M6, they hit them WAY too hard. If you have an auto, you can get low 1.7x's with street tires, and high 11 second ET's. Trust me, I know.

Just glancing at your numbers, I think that in cold air, with good tires and good driving, you could realistically see 12.2x's or 12.3x's, but it'd have to be a perfect run.

Start saving for a rear now since you're an M6 though.
